/var/log/nginx/error.log exist but it is empty.

Is it maybe writing on another location?

Greetings!

This typically indicates that a back-end service is not listening, which Nginx is relying on to serve the content. This could be anything from PHP-FPM to a Node.js app. Though I can’t say which it is without seeing the logs, I can say that starting that service manually will likely resolve the issue. If your service uses systemd, it can be made to start on boot. For example, if the server were named “php-fpm” I could run:

systemctl enable php-fpm

sorry, i missed to see the following line on the error log:

nginx: [warn] conflicting server name “www.myweb.com” on 167…***:80, ignored

No idea how to solve this.

Thank you for your help.

ok, site is up.

After rebooting some of the services were down - including apache, so after starting all of it, it is working.

Will investigate more, but for now its ok.

Thanks all
